Macromolecular biosynthetic parameters and metabolic profile in different life stages of Leishmania braziliensis: Amastigotes as a functionally less active stage
(Public Library of Science, 2017)
It was recently hypothesized that Leishmania amastigotes could constitute a semi-quiescent stage characterized by low replication and reduced metabolic activity. This concept developed with Leishmania (Leishmania) mexicana ...
RNA-Binding Proteins in Trichomonas vaginalis: Atypical Multifunctional Proteins
(MDPI, 2015)
Iron homeostasis is highly regulated in vertebrates through a regulatory system mediated by RNA-protein interactions between the iron regulatory proteins (IRPs) that interact with an iron responsive element (IRE) located ...
New insights on the role of lipid metabolism in the metabolic reprogramming of macrophages
(Frontiers Media, 2020)
Macrophage activation is intimately linked to metabolic reprogramming. Inflammatory (M1) macrophages are able to sustain inflammatory responses and to kill pathogens, mostly by relying on aerobic glycolysis and fatty acid ...
The energetic cost of mounting an immune response for Pallas's long-tongued bat (Glossophaga soricina)
(Peerj Inc, 2018-06-05)
The acute phase response (APR) is the first line of defense of the vertebrate immune system against pathogens. Mounting an immune response is believed to be energetically costly but direct measures of metabolic rate during ...
Post-treatment vascular leakage and inflammatory responses around brain cysts in porcine neurocysticercosis
(Public Library of Science, 2015)
Cysticidal treatment of neurocysticercosis, an infection of humans and pig brains with Taenia solium, results in an early inflammatory response directed to cysts causing seizures and focal neurological manifestations. ...
Meal size effects on the postprandial metabolic response of Bothrops alternatus (Serpentes: Viperidae)
(2013-07-15)
We examined the effects of meal size on the postprandial metabolic response of the lancehead Bothrops alternatus (Duméril, Bibron & Duméril, 1894), fed mice equaling to 5, 10, 20, and 40% of the snake's body mass. The ...
Sulfur Metabolism and Stress Defense Responses in Plants
(2015-12-01)
Sulfur management is an important issue in crop plant nutrition. Sulfur has a role in fundamental processes such as electron transport, structure and regulation. It is also associated with photosynthetic oxygen production, ...
The interplay between ambient temperature and salt intake affects oxidative status and immune responses in a ubiquitous Neotropical passerine, the rufous-collared sparrow
(Elsevier Inc., 2019)
© 2019 Elsevier Inc.Physiological traits associated with maintenance, growth, and reproduction demand a large amount of energy and thus directly influence an animal's energy budget, which is also regulated by environmental ...
Coping with salt water habitats: metabolic and oxidative responses to salt intake in the rufous-collared sparrow
(Frontiers media SA, 2017)
Many physiological adjustments occur in response to salt intake in several marine taxa, which manifest at different scales from changes in the concentration of individual molecules to physical traits of whole organisms. ...
Cholesterol metabolism: Increasingly complex El metabolismo del colesterol: Cada vez más complejo
(2012)
Cholesterol is an important molecule; it is necessary for the biosynthesis of steroidal hormones, bile salts and to maintain the stability of biological membranes in animal cells. However, its excess is negative and is ...
